They acquired former Philadelphia Eagles backup Bryce Brown on Saturday for a conditional future draft pick and a swap of seventh-rounders.

The Eagles announced they'll get a fourth-round pick in 2015 or a third- or fourth-rounder in 2016 in the deal.

The Bills get Brown, a seventh-round draft pick out of Kansas State in 2012 who has run for 878 yards and six touchdowns on 190 carries (4.6 average) over two NFL seasons.

They already have C.J. Spiller and Fred Jackson on the depth chart and signed Anthony Dixon to a three-year, $3.5 million deal in March.

Jackson, 33, is due a $2.45 million base salary and can earn another $1.35 million in bonuses and incentives in the last year of his contract. Spiller is entering the last non-voidable year of his rookie contract.
